rlhis invention relates to improvements in animal guards andparticularly to those used to prevent cattle, or similar creatures fromstraying into areas which are not adaptable t; for fencing, as railroadand highway crossings, or passageways between adjacent pastures and thelike.

lts object is to provide an improved means tor accomplishing the abovedescribed purposes which shall be more etl'ectual than the devices nowin common use, and shall, not only hamper the -animals attempting topass over the device, but also alarm them by indieting slightly painfulcontacts with the toet and the legs of the said animals.

Vlihe manner which the above objects are attained and the mechanicalcharacteristics of the invention will be' fully described in thelitollowing speciiication. and illustrated in the so accompanyingdrawings, in which:

Fig. 1 shows a front elevation of the elements of the device as appliedin conjunction with a railroad track, the view being taken on the line1-1 of Figure 2.

Fig. 2 shows a plan view of the elements illustrated in Figure 1.

Fig. 3 shows a orm of the invention somewhat enlarged, in which certainparts are slidably mounted, the view being taken on the line 33 ofFigure 4.

Fig. e shows a plan view of the mechanism illustrated in Figure 3 of thedrawings.,

Referring tirst to Figures 1 and 2, the device eomprises a series ofspur wheels as shown at 10, 11, 12, 13 etc., which are rotatan blymounted on rods as shown at la and 15. Collars as seen at 16, 17 etc.are provided to maintain the said spur wheels in position.. rlhesupporting rods are mounted in vertical bearing brackets as shown at 19,20 etc., which are secured to base strips as seen at 241 and 25. 'llhesestrips are secured to the railn road ties as seen at 26 and 27, or toany suitable supporting medium. Railroad tracks 28 and 29 are showntogether with the ties 26 and 27 to illustrate this form ofinstallation, they are not elements of the invention, which may haveother applications than that shown in connection with a railroad. rlFhedevice may for instance, be built on a smaller lill Serial No. 264mm.

scale and used to protect certain spaces from the intrusion of dogs andother small animals.

lhe mechanism above described may be constructed ot' iron, or of anysuit-able mate- 55 rials, provision being preferably made to preventrust, or corrosion from interfering with the working parts theeot.

The form illustrated in Figures 3 and f1 is constructed with the rods as111, 15 etc., mounted in slots as seen at 3l and 32 in the verticalsupports and 34E, which supports are the equivalent of the bracketsshown in the preceding figures at 19 and 20. 0n the rods so mounted arelinks as seen at 35 and 3G which support the foot pla-tes as seen at 37and 38, these links being placed at intervals along the said plates asrequired.

1t will be seen that should an animal try to pass over the guard asshown, the contact ol its reet, or hooiis with the spur wheels wouldgive such discomfort as to cause it to withdraw and abandon the attempt.l1`he dis comfort and retarding ed'ect of the device as shown in Figures1 and 2 would be greatly augmented by the arrangement shown in Figures 3and Al in which case a hoof placed on the toot plate would immediatelydraw the adjacent spur wheels against the sides of the animals legthereby applying the same startling treatment as is given by anequestrian wearing the conventional i'orm of s urs.

rlhe spur wheels may, if desired, be hrmly secured to the rods, whichwould then rotate in the bearing brackets. This modilicasa tion andsimilar minor departures in t'orm, or construction may be made withinthe spirit and scope or the appended claims.

Having thus described my invention, what ll claim as new and desire tosecure by lietA an ters Patent, is as follows:

1. lin an animal guard, a series of rods placed parallel to each otherand slidably mounted in vertical supporting members which are secured toa suitable base structure, rotatable members having spur points projecting radially therefrom and the said rotatable members mounted atintervals on the aforesaid rods, and foot plates positioned in thespaces intervening between the said rods 1 and supported by links whichconnect them foot plates in positions parallel to the said to adjacentportions of the said rods. rods and supported therefrom by link mem- 2.In an animal guard, parallel series of bers which are placed atintervals thereon. l0 spur Wheels rotatably mounted at intervals Intestimony whereof I have aflxed my sig 5 on rod members which areslidably support,- nature.
